Opening SIG files

Did your computer fail to open a SIG file? We explain what SIG files are and recommend software that we know can open or convert your SIG files.

What is a SIG file?

Files that contain the .sig file extension are small text files that contain an email "signature" that has been created by an email user. These files can be automatically attached at the end of a user's email messages, allowing them to send emails without having to retype the signature information each time the email is sent.

SIG files are often used for business emails and normally contain the name of the user, their email address, the name of the company they work for, their title and their contact information. In some instances people will use SIG files for personal emails, including their name, email address and a personal statement at the bottom of each email.

Many email programs allow a user to create multiple SIG files. The user can then choose which sig file to use when sending an email, or they may choose not to attach any signature at all.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.

What is a file extension?

A file extension is the characters after the last dot in a file name. For example, in the file name "winmail.dat", the file extension is "dat". It helps Windows select the right program to open the file.
